ping test
I always suggest this to people who are having potential wifi issues.
Open up command line
type : Ping <ip address of your router> -t
that will do a continuous ping so you can see if your connection to your router is dropping.
Since you can open more then one cmd window do the same thing to your feed address as well.
If you see it drop on the feed address and not the router issue that means you have a problem with your iso, If it drops on your router ip then you might have a wifi issue.
you can leave these pings going overnight to stop the ping hit CNRL - c it will give you stats of how the ping did.
